Nigel Stepp writes: The reason IPv6 has not been deployed after a decade is still hotly debated. Vint Cerf has now publicly cited lack of ISP support as the primary roadblock, which has been one opinion. Coverage of the IPv6 issue in mainstream media has been rare, and such a notable figure publicizing it in these terms will most likely shape how the next few years unfold.

From the BBC News article, 'Internet Service Providers urgently need to roll out the next generation of net addresses for online devices, internet pioneer Vint Cerf has said.'

Specifically, Vint seems to think creating user demand is essential: 'The reason [ISPs] haven't — which is quite understandable — is that customers haven't asked for it yet," said Mr Cerf, adding, "my job, whether with my Icann hat on or not, is to persuade them to ask for it.'
